A Walking Tour of Papal Rome

In order to keep track of my bags, I use a small metal bell--the kind dancers from India wear on their ankles. I thread it with fishing line and tie it to my carry-on. If anyone touches my bag after I set it down, the bell chimes. It's not a very obtrusive sound, but it's distinctive enough for me to notice if a thief is trying to get into my things. The same bell can be hung on the doorknob inside your hotel room.

Don't rush off the car-rental lot. Before driving away--especially in foreign countries where the controls might be unfamiliar-test the headlights and brakes, and look for the extra tire and changing tools. I once had a rental with malfunctioning brakes in Mexico and caused a minor accident--one that could certainly have been avoided had I checked them properly before leaving the lot.

Whenever I'm in a country where drinking or brushing my teeth with the tap water is a risk, I cover the faucet handles in my hotel bathroom with a towel. As a result, I never accidentally turn on the faucet when I'm half asleep.

A company called Orikaso makes brightly colored polypropylene sheets that can be folded--kind of like origami--to form a dish, bowl, or cup. The sheets are lightweight and reusable, and you simply flatten them when you're finished. We found ours at a sporting goods store, but you can also buy them online. Check orikaso.com for retailers.

I try to avoid checking any luggage, but the airlines are getting stricter every day about the size and weight of carry-ons. So when I pack, I put any important stuff in a plastic bag and place it in a front pocket. If I'm told to check my carry-on when I get to the gate, I can just pull out the smaller bag and board.

After I fell into a stream in Cambodia, my digital camera wouldn't work. Someone suggested leaving the camera in a bag of rice overnight to draw out any condensation. By the next morning, it was dry and working perfectly.

If you take an overnight flight to Europe and early check-in at your hotel isn't an option, ask the concierge if you can store your luggage until later in the day and use the hotel gym's shower. You'll be refreshed and ready for sightseeing. Pack toiletries and a change of clothes in your carry-on.

Online check-in isn't just for airlines. After reserving an Alamo car over the Internet, I was offered online check-in just by entering my credit card number and driver's license information for approval. At the airport, following Alamo's instructions, I informed the shuttle-bus driver that I had checked in online and reserved an economy car. I was dropped off in the lot and told to pick whichever car I wanted. I drove it to the exit, where my credit card and driver's license were verified on the computer, and I was done.

I work for a major airline and can attest to this tip for redirecting lost luggage. Place a copy of your itinerary--including contact info for where you're staying--inside your checked suitcase. If name and flight tags are missing, we'll still know where your bag needs to go.

If you book a package over the Internet, print out all the details of what's included and take it with you. When a hotel desk clerk in Paris said that the breakfast buffet we had enjoyed for the previous seven mornings was not included in our package, I was able to show him the printouts and prove him wrong. He apologized profusely and wiped the breakfast charges from our bill.

If you plan to buy crafts in a country where bargaining is expected, use the time it takes for luggage to be unloaded to scope out the airport stores. Jot down items you like and their retail prices. If you find a similar item while touring the country, you have a top-end bargaining point. If you don't find the object at a better price, you can always pick it up at the airport while you're waiting for your flight home.

We were told by an airport security official to tape a business card onto the cover of our laptop. Turns out he has an average of six laptop computers left behind each day! There are so many more procedures now--removing shoes, removing coats--that people forget when they send their laptop through in a separate bin. The official added that it's very difficult to return them because most laptops have passwords that keep the owners' personal information hidden.

Once the hotel shampoo bottles I always seem to bring home are empty, I refill them with my own brand of shampoo, conditioner, and shower gel--instead of buying travel-size containers at the drugstore. I toss them, along with other small items (toothbrush, toothpaste, nail file, pillboxes, and a comb), into a medium-size Ziploc bag, and I'm ready to go; the clear plastic lets me find things easily.

Read the fine print on your rail pass. You can often use it to save money on other modes of public transportation. With a Scandinavian rail pass, for example, you'll pay less to ride the ferries. In Switzerland, a rail pass can get you free bus rides, as well as complimentary entrance to museums and discounts on funiculars and hotel accommodations.

When I'm on the road, I often have to use the hotel iron before heading out to business meetings. But getting water into the iron can be a hassle--most irons won't fit under the sink faucet, and using a glass to pour water into the tiny hole is nearly impossible without spilling everywhere. There's an easy solution: Use the carafe from the coffee maker. Just be sure the carafe is clean, or you could end up with coffee stains on your clothes.

Don't assume a single room costs less than a double one. I booked a hotel in Spain online and noticed that rates were the same whether I booked a single or a double, but the single was much smaller and its bathroom had only a small shower stall and no tub.

When we come home at night, my wife and I each take a dollar from our wallets and put them in a special spot. We deposit what we've collected into a travel account at our bank every few months, so at the end of a year, we have $730 toward our next vacation—not counting interest.

Love researching your destination online, but don't know how to organize all those printouts, maps, guidebooks, and tips? I get a 5 x 7" spiral notebook (Mead makes one with a sturdy cover and a pocket insert), a set of index tabs, and some glue. Divide the notebook into sections with the tabs (sights, maps, currency converter, restaurants, etc.). Photocopy—in reduction mode—all the info you want to bring, and glue it into the appropriate section. I leave plenty of pages for my journals. This creates an all-in-one personal guide that you can read again years after your trip!

If you're traveling with a companion, pack half of your belongings in his or her suitcase and vice versa. This way, if one piece of luggage gets lost, you'll each still have some clothing.

I reverse the batteries in my portable CD player before packing it in my suitcase or backpack, in case it's accidentally turned on when my bag is jostled. I came up with the idea after arriving at my destination to find that the brand-new batteries I'd put into my Walkman were dead.

Check fares periodically after booking your airfare. The airline may have a sale, and buying new tickets could save you money, even after you pay the change penalty. My wife and I used Travelocity's Fare Finder to pocket $187 each on a recent trip from Seattle to New York City, simply by re-ticketing.

Every summer, we drive out West from Pennsylvania with our two kids. To avoid that infamous road trip question ("Are we there yet?"), I give each child a map with our route highlighted on it. Along the way, they can match up the town names with road signs we pass, and that way, they always know exactly where we are and how much farther we have to go until we'll get there.

Don't assume you can save a spot at the pool with your towel. Cruise lines give you one pool towel at the start of the cruise. If you don't have it (or a cleaned trade-in) at the end, you'll get charged. If you let it out of your sight, you run the risk of losing it or having it stolen by a fellow cruiser.

My husband cut an old contact lens case in two and uses the halves to carry his medication when we're traveling. He prefers them to regular pillboxes because lens cases are watertight and compact enough to carry inside a shirt pocket.

If you know you'll be cooking while on vacation, bring along small amounts of the spices you need for your favorite recipes. You'll save by not buying large containers of spices.

I live in coastal Florida, where the electricity sometimes goes out during violent storms. Before a trip, I place a few ice cubes in a plastic bag and put the bag in the freezer. If the ice has melted and refrozen by the time I get home, I'll know we've had a power outage and that any food left in the refrigerator may be unsafe to consume.

I always snap photographs of scenic highway markers, park entrance signs, and the like. These informational photos are put into our album to help identify the many sites that we visited.

During a visit to Mexico City, I was sitting in a plaza near a fountain, watching the locals stroll around in their Sunday best. Nearby, an older gentleman was playing a concertina; his music perfectly framed the scene. I took lots of pictures, but I didn't have a way to capture that music. Now I pack a small tape recorder along with my camera.

For overnight flights, pack a few Oral B Brush-Ups in your carry-on. Before the plane lands, you can "brush" your teeth, leaving you refreshed and ready for the day!

Many tourist information offices provide discounted same-day booking services for local lodgings. My husband and I discovered this when we accidentally left a midweek gap in our travel plans between my husband's conference hotel and our B&B in Charleston. Instead of adding another night at either location, we stayed at one of the more elegant inns (normally over $200) for $70, courtesy of the Charleston Convention and Visitors Bureau.
